Southern California -- this just in

Michael Jackson, who died of an overdose of a powerful sedative, was "probably" in denial about his drug abuse, his sister Janet Jackson said in an interview.

In an interview with ABC News, Jackson said the family was aware of the pop star's drug problems and in the past had organized interventions for him.

"You can't make them drink the water," Janet Jackson said. "I'm a true believer in prayer,
a big believer in prayer -- but it's, it's something that you can't do
for them. Something they have to do for themselves."

Asked about whether Michael Jackson believed he had drug problems, his sister added: "I felt that he was in denial."

Jackson died of "lethal levels" of
the powerful anesthetic propofol, according to a search warrant
affidavit unsealed in Houston.

Conrad Murray, Jackson's personal physician, told Los Angeles Police Department detectives that he had been treating Jackson for
insomnia for about six weeks. He had been giving Jackson 50 milligrams
of propofol every night using an intravenous line, according to the
court records.

But Murray told detectives that he feared Jackson was forming an
addiction and began trying to wean the pop star off the drugs. He
lowered the dosage to 25 milligrams and mixed it with two
other sedatives, lorazepam and midazolam. On June 23, two days before
Jackson's death, he administered those two medications and withheld the
propofol.

On the morning Jackson died, Murray tried to induce sleep without
using propofol, according to the affidavit. He said he gave Jackson
valium at 1:30 a.m. When that didn't work, he said, he injected
lorazepam intravenously at 2 a.m. At 3 a.m., when Jackson was still
awake, Murray administered midazolam.

Over the next few hours, Murray said he gave
Jackson various drugs. Then at 10:40 a.m., Murray administered 25
milligrams of propofol after Jackson repeatedly demanded the drug,
according to the court records.
